FTIR spectra of pure and Cu-substituted nanoparticles and scaffolds. (A) determinant peaks of HA were detected in all nanoparticles without impure bonds. (B) the presence of nHA, Cs, and Gel were verified in the FTIR spectra of scaffolds. Moreover, chemical bonds were found between Cs/ cross-linker and Gel/ cross-linker (1552 cm -1 and 1639 cm -1 respectively) and Gel/nHA (1321 cm -1).
